This is a security measure Librewolf has. You can fix this in the settings.
I'll update with the steps to fix this. Hold on.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
Rules
- Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.

This comes from Canvas being blocked by default in librewolf. You can either enable it globally in the settings, or enable it per site by clicking the little picture icon in the URL bar and toggling it, then reloading
Thanks! It worked now all my PFPs match!
Yay glad that fixed it for you!

You most likely need to enable Canvas support on that site for the upload. It's a little picture icon right to the left of the URL bar. I would recommend reading the docs above.
Are you using a vpn or Tor by any chance? I get that exact "image" when I upload through Tor
- What's a PFP?
- What format are you uploading them in?
- What app are they generated with?
- Do they also look corrupted on other devices you may have handy?
1: PFP in this context means Profile Picture 2: I've tried .png .jpeg & .webp 3: I used Krita to make the image 4: I don't have anything else I could use
Are you just SAVING as these file extensions, or EXPORTING as each type of file extensions.
Not the difference, and see in the File menu that you need to use the EXPORT function to change actual file type.
This issue has been solved already (it was because WebGL was disabled), but I did go through the time re-exporting the image in the different file types.
